Does/How/Will unity support surrogate pair?

I found the unicode of some emoji characters on Android/iOS are larger than 0xFFFF (eg: U+1F40C).
But the method "Font.GetCharacterInfo" can get info only from one char parameter.
So is there a way to get these emoji characters info in unity?

 

So it's the mono framework you're going to want to research for specifics on. Not unity specifically. Becuase unity uses the mono framework.

Now if you're dealing with text that has characters with a value larger than 0xFFFF, that means you're dealing with UTF-32 encoding. The 'string' and 'char' types in .net/mono are UTF-16 in size, which is why 0xFFFF is the largest value supported.

You can deal with the text data by keeping it in a byte array or something like that and directly manipulate it there.

You could even write a special string type around this if you wanted. Or you might be able to even find an implementation out there.

 

I think my title confuses the problem.
The problem is the first parameter of the method "Font.GetCharacterInfo" require the type "char".
So I can't get the glyph from the font, if the unicode is larger than 0xFFFF.

 

Aw, well in that case, you're probably S*** out of luck.

 

Just added support in TextMesh Pro for UTF-32. The built-in Font Asset Creator now supports generating font assets with UTF-32. You can then access those characters by using the "\U" with 4 hex pairs. See the example below.



Note: This example also show the use of the <font> tag which will be available in the next release of TextMesh Pro. Since the font asset that I generated only includes icons (like that fish), I used the <font> tag to access another font so I could type text.
